July 8, 2011 — The best chance to rub elbows with royalty this weekend is going to be through a group called Tusk Trust.

As Los Angeles braces for the Friday arrival of Prince William and Kate Middleton, details are emerging about the couple’s most intimate affair — a Sunday morning reception for the African wildlife conservation group.

William and Kate will mingle with a group of 45 long-time U.S. patrons of the charity. It’s the couple’s only private engagement during their weekend trip to Los Angeles.
